Embodiment Construction
[0060] The technical solution of the present invention will be further introduced below in combination with specific embodiments.
[0061] This specific embodiment discloses a dynamic linearization system of a power amplifier based on pattern recognition, such as figure 1 shown, including:
[0062] Eigenvector generating module: used to generate an eigenvector representing the current state of the power amplifier;
[0063] Multi-layer perceptron module: perform pattern recognition on the eigenvector of the power amplifier, and obtain the pattern recognition result of the current state of the power amplifier;
[0064] Predistortion coefficient lookup table module: according to the identification result of the multi-layer perceptron, the index corresponds to the predistortion coefficient of the current state of the power amplifier, and generates a predistortion signal corresponding to the current state of the power amplifier;
[0065] Vector signal module: used to generate the...
